The plows 1,0 are mounted respectively on `standards'11"a`nd 1,2. Each stan-dard is secured to the beam l by clamps one part l13 of vwhich, is preferably integral with the standard, and to which the second part 14 is securedby suitablebolts which can be readily loosened to permit adjustment of the standards'andtheplows lalong the beamto regulate the width of furrow it is desired to cut. f On the casting 4 is a bearing 15 in which is slidably supported the vertical spindle16 of a crank axle having a furrow wheel 17 'j ournaledon its lower vend. A split elbow 18 is rigidly secured on the bend of the aXle and vbolted tothe elbow 18 is a forwardly extendn ing bar'19 normallyparallel with a draftfbar, formed of parallellbars' 20 and 21, having its "rear en'dsecuredto a coupling 22 by a verti'- calfpivot 23,and` its forward end adapted to bel attached to a tractor. ,The coupling 22 `is pivotally connected to a clevis 24 bolted to the rdraw bar 8, the latter having a series "of holes 2,5 for lateral adjustment of the clevis as `oecasionmay require. A bar 26,

'composed of superimposed bars 27 and 28 ing 29 and journaled therein is a rock shaft a' having itsffurrowward end 30 bent to eX- tendforwardly and pivotally kconnected to a vertically disposed'vrod v31 threaded aty its f upper end to engag-e with a threaded opening fin an eye-bolt 32 and secured from longitudinal movement by a nut on the end of the rod. vThe eye-'bolt`32 ispivotally secured in a cap loosely mounted on the upper end vof the spindle `16 in order thatl the latter may vturn freely therein; withdrawal of the spinelle from the cap is prevented by a collar-34 which is krigidly secured to the spindlel by a set screw 35 which projects through a hori-y Y zontal slot 36 in the cap 33.

'A manuallyoperable lever 37 is rigidly supported a bell crankl`47 reenforced by a connected to one arm of a bell vcrank 38 pivotally mounted on the shaft a. A notched sector 39 is loosely supported on the landward end of the shaft a and is xedly secured to a bracket 4() rigidly mounted on the cast,-

ing 4; Athe lever37 is provided with the usual` `type of latch to engage with any one of the notches in the sector 39. Pivotally connected to the rearward arm of the bell crank 38 is abar'cvwhich extends rearwardly to 'an arm 41 on the furrowward end of acrank axle 42-y and preferably integral therewith.; The

crank axle 42 is rotatably journaled inisuit-V able bearings on the casting 2 and extends transversely of the plow'. On thelan'dwa'rd or crank end of the axle v42 is mounted av landwheel 43 with respect to which the frame is raised or lowered by operating the lever 37 to rock the axle 42. v y v On a rearward extension 5 of the casting 2 is a bearing 44 in which is slidably and rotatably journaled a vertical spindle 45 forming part of a crank axle on the crank end of ywhich is mounted the rear furrow `wheel' 46.

On the end of the extension Z; Vis pivotally brace 48 which is secured to the pivot of the bell'crank and extends parallel with the lat* ter to its rear termination, the brace isthen bent upon itself toward the bell crank andis l securely bolted thereto. To the forward arm of the bell crank 47 5a vertical rod 49 ispiv- Aotally attached, the Vupperend of said lrod is threaded to engage with the threadedeyeof abolt 50 whic'his loosely held` in a transverse hole ina cap 51, mounted on the upper end of the spindle 45, and held therein byl a pin or l' cotter. The cap 51 is held on thevspindle 45 by a collar .52 rigidly secured on the Vspindle by a set screw 53 which extends'through a horizontal .slot 54 in the cap 51. f y

Pivotally connected to the rear 'arm of the bell crank 47 is a link 55 which extends forwardly to connection with an 'upstanding arm.

56 v`preferably integral with a'rock shaft 57 parallel with theaxle 42 and supported in bearings 58 and 59 on thev casting 2. At the pivotal connection of the link with the arm 56 is connected a bar 60 which extendsforwardly to rpivotal attachment to yan arrn61v whichV is part of a manually operable lever 62 pivota'lly'mounted, at the bend of the army 61-on a standard 63 rigidly secured lon they shaft a. To the pivot of the lever 62 is se a coiled spring v69 the other end of which is connected to a loop whichpasses around the standard 63 and is secured to on the rear side thereof. i

n The traction power of the landwheel 43 is utilized to raise the furrowward side of the plow only, by the operation 'of mechanism:

wellknown in the artv andinclwudinga clutch 82 Vand 83L respectively, (Fig. 1) both concen-V t-rically'mounted in alinement with the land wheel, theH driving partf82fbeing! secured to the landwheelfand thedriven part 83 being` connectible to the rst part at will by actu-y ation of a tripping rlever 711 controlled by a cable72` fromthe tractor by which the plow is to be drawn. The liftingjlink 73 in/this instance'extends fromy'the second part of the.

clutch to connection with anarm74prefera projection l Vcomprising driving and driven clutch parts ably integral with the landward rend ofthe rockshaft 57 and projecting` upwardly theree l from. f

rocked forwardly and through the arm 56,

preferably integral therewith, the bars 55"l .c

and 60 are also moved in a forward direction. c

The forward movement of the bars l55 and i i 60 rocks the b'ell'crank 47 Tand"simultaneously LV i the shaft a through the standard" 63, rigidly mounted thereon, and carrying the`leverh62 to thebent end "of which the bar 60 isfpivot-` ally connected, the lever 62,k when locked to,

the sector 64,7acting practically asacontinyuation Vof the bar60,and as the sector 64 is pivotally supported on the standard '63 and the pivoted link 65 it.Y moves forwardly with the movement of the barsy 55-and V6.0 so' that its relative position with the lever 62 is never disturbed. Asl heretofore kexplained thev bell crankf47 is connectedtoa rod 49 attached to a cap 51 on the upper end of thespindle 45 A' of the rear furrowwheel' axle, and the arm 30 kofthe rock shaft a is connectedto a simi lar rod31 attached to a `cap33 on'the upper 47 and the shaft a are rocked' thefurrowward side of the plow isfraised moving Yupward freely on the spindlesll6 and 45, the operationbeing` materially assisted bythe coiled spring '69 and a similarfspring? 5 extended between a bracket 76 on thebell crank 47 and a bracket 77 kon the arm '41 of the axle 42.

i The depth at which it is desi-red the plow shall operate iscontrolled'by the levers 37 ".1515 .v Vend of the spindle 16 of the frontfurrowwheel axle; consequently when the bell crank y vand 62, they lever 62 operating to raise or lower *l the'furrowwardside of the plow. on the front furrow wheel through the connections' therewith described, andthe lever-37 operating f .I
